Please solve this question i will rate you Probability and statistics are related areas of mathematics which concern themselves with analyzing the relative frequency of events. Both subjects are important, relevant, and useful. But they are different, and understanding the distinction is crucial in properly interpreting the relevance of mathematical evidence.

You are working with a local business helping them to be more cost effective. Over the past 10 years, they have seen an increase in expenses due to lighting cost. As such they have decided to buy bulk lighting for the building offices and keep them in storage in the basement. Use what you know about statistics and probability to answer the following questions. The front lobby has a decorative chandelier which holds 5 candelabra bulbs. Light bulbs are installed successively so that if one bulb blows out, all of the bulbs are replaced. If these particular light bulbs have a mean lifetime of 2 months with a standard deviation of 0.25 months (per the manufacturer), determine the probability that this box of 40 lightbulbs will last for 5 years.
Please solve practice question 2 and show the steps for the required areas. Please and thank you.
